Fleck Injector, #2 7000, 5810/12 Valve

This genuine Pentair Fleck Injector, size #2, fits 7000-series and Fleck 5810/5812 control valves and provides the brine-draw suction your softener relies on during regeneration. As water flows through the injector's precision venturi, it creates the vacuum that pulls salt brine from the tank into the resin bed, where ion exchange recharges the media's softening capacity. The part belongs to the Fleck Injector service family and is matched to the 5812 valve.

Sizing the Injector

Each numbered injector corresponds to a specific range of tank diameters and flow conditions. The #2 sits in the middle of the lineup, suited to medium-capacity systems that need more draw than the smaller sizes provide but less than the largest. Installing the correct size ensures the brine is drawn at the right rate for a thorough, efficient regeneration. Too small an injector for the tank can starve the bed of brine, while too large a one can disrupt the proper draw timing, so matching size to the system specification matters.

Injector fouling from scale, sediment, or iron is a leading cause of softeners that cycle but no longer soften, because little or no brine actually reaches the resin. The telltale sign is a brine tank that stops drawing down combined with hard-water symptoms returning around the house. Swapping in a fresh #2 injector is a fast, affordable repair that often resolves the issue completely. Confirm the size matches your tank before installing, clean or replace the injector screen at the same time so the new injector doesn't clog immediately, and relieve system pressure before opening the injector cap. A correctly sized, clean injector is one of the simplest ways to keep a Fleck softener performing reliably. Because the injector is inexpensive yet central to the whole regeneration, keeping the correct size on hand for your system turns what could be a frustrating service call into a quick, low-cost fix.
